Problems solved by technology

In the wind tunnel test, due to the relatively low Reynolds number of the test, there is a rather long section of laminar boundary layer on the surface of the model, which causes a large difference between the state of the boundary layer on the surface of the model and the real aircraft.
This difference complicates and irregularizes the influence of Reynolds number in wind tunnel tests

Abstract

The invention provides a transition belt cutting and bearing device and belongs to the field of transition belt production. The transition belt cutting and bearing device comprises a frame body and a bearing part; a mounting space with a top opening is formed in the frame body, the bearing part is arranged in the frame body, and a negative pressure opening used for being connected with a negative pressure device is further formed in one side of the frame body; the bearing part comprises an adsorption net plate and a position adjusting assembly, and the position adjusting assembly comprises a telescopic rod and a bearing plate; one end of the telescopic rod is fixedly arranged with the bearing plate, and the other end of the telescopic rod is fixedly arranged relative to the frame body, so that the bearing plate can be relatively close to or far away from the top opening; and the adsorption net plate used for bearing a transition belt is placed on the bearing plate.

Description

technical field [0001] The invention relates to the field of transition belt production, in particular to a transition belt cutting and carrying device. Background technique [0002] When a real aircraft is flying in the air, due to the high flying Reynolds number, the boundary layer on the surface of each part of the aircraft is almost all in a turbulent state. In the wind tunnel test, due to the relatively low test Reynolds number, there is a rather long section of laminar boundary layer on the surface of the model, which causes a large difference between the state of the boundary layer on the model surface and the real aircraft. This difference complicates and irregularizes the influence of Reynolds number in wind tunnel tests. If the method of artificially fixing the transition of the boundary layer is adopted during the model test, so that the boundary layer on the surface of the model is similar to that of an airplane, the correction of the influence of Reynolds numbe...
